目的:从电力线载波通信系统中提取随机脉冲噪声并分析其来源。方法建立一个简单的检测随机噪声的测试系统。结果 FSV 方法可以成功地识别热水壶在电力线上造成的随机脉冲噪声,同时也证明了统计分析的方法对于识别随机脉冲噪声效果不佳。结论可以通过对 MAF-FSV 方法结果设定阈值来识别低压电力线载波通信系统中的随机脉冲噪声,进而可以确定低压电力线网络拓扑结构的改变。
Objective To extract the asynchronous impulsive noise from the power communication line and obtain the source of particular kind of noise. Methods A simple measurement system was constructed to detect the asynchronous im-pulsive noises. Results The Feature Selective Validation (FSV) method was able to successfully recognize the impulsive noise produced in the power line by the connection of a kettle. Meanwhile, the statistical analysis was proved useless in the recognition of asynchronous impulsive noise. Conclusion The asynchronous impulsive noise in the low-voltage power com-munication line could be recognized by setting threshold values for the results of MAF-FSV method, and the change in the topological structure of the low-voltage power line network could then be determined.

目的综合了解树鼩的分泌蛋白的信息。方法利用真核生物分泌蛋白预测流程EuSecPred 2.0对树鼩的分泌蛋白进行全基因组预测,并对获得的分泌蛋白及所携带的信号肽进行系统分析。结果树鼩全基因组蛋白基因中鉴定获得279个分泌蛋白,占基因组全部编码基因的7.2%。对其功能和结构域进行注释分析,发现了以水解酶类、行使蛋白结合与离子结合功能蛋白质及初级代谢过程相关蛋白为主的分泌蛋白。氨基酸组成分析表明,树鼩分泌蛋白及其信号肽主要由疏水性氨基酸组成,信号肽剪切位点有部分亲水性氨基酸的存在。基序分析发现,分泌蛋白信号肽中未存在保守基序,而分泌蛋白内部存在GxHxCGG[FSV]L[IV][RAS][EP]D[WF]VLTAAHC、[KG]PPGV[YF]T[RK][VI][SC]x[YF][VL][DS]WIQx[TV][MI][RK]、[DT][SA][CF][QK]GDSGGPLVCNGV[LA]QG[IL]V、GY[HL][FL]CGG[SAT]L[ILV]S[EDP][CR]WV[LV][TS]AAHCF、N[IV][FI]FSP[LV]S[IV][SA][TA]ALAMLSLG[AT]xNDTLTQ[IL]L[EQ][GV]LGF[ND]LT[ES]T[SP]E 5种基序。结论在全基因组范围对树鼩分泌蛋白进行预测分析,有助于进一步研究树鼩机体功能调控机制及动物模型的开发。
